 I've got following error during 'make' (in MinGW at Windows):
 {{{libpostproc/postprocess_template.c: In function ‘dering_MMX2’:
 libpostproc/postprocess_template.c:1045:5: error: can’t find a register in
 class ‘GENERAL_REGS’ while reloading ‘asm’
 libpostproc/postprocess_template.c:1045:5: error: ‘asm’ operand has
 impossible constraints}}}
 Using commit ba353436a375b92659366aeec8c0139da08f8a0b. Configure string:
 ./configure --prefix=build --enable-gpl --enable-w32threads --enable-
 runtime-cpudetect --enable-memalign-hack --enable-libx264 --enable-shared
 --disable-static --disable-optimizations --disable-mmx --disable-stripping
 --extra-cflags=" -I/c/ffmpeg/x264/staticbuild/include" --extra-
